Common Specifications (applies to all CPF fittings in this datasheet)
DESCRIPTION
CPF is an improved cone type fitting system that adds a unique o-ring sealing system which permits leak free
connections without tools. CPF fittings can be directly connected to ¼" medium pressure cone type fittings from
other manufacturers*, provided that wrenches are used to complete the connection. The fittings of the CPF system
have been designed and tested to comply with ASME B31.3-2008, Chapter IX: High Pressure Piping.
PERFORMANCE
Maximum Allowable Working Pressure (MAWP): 10 000 psi / 700 bar / 70 MPa
Finger-tight: -20 to 50°C
Wrench-tight: -40 to 150°C
Minimum Hose Bend Radius: 1.0" (25mm)
CONSTRUCTION
Thread Type: 7/16-20 UNF 2B
Cone Angle: 60°, nominal
Fittings: High Strength 316 Stainless Steel
Hose: Polyamide core with urethane jacket
External Hose Diameter: 0.235" (6 mm)
Internal Hose Diameter: 0.08" (2 mm)
Hose Weight: 0.0179 lbs/ft (26.6 g/m)
CPF Female O-rings: AS568A-012, Viton® 80 or 90 #3981
O-ring Lubricant: Molykote® 55
RECOMMENDATIONS
Thread Lubricant: Use a process compatible fluid Wrench Torque: 100–140 in-lbs (11.3–15.8 Nm)
U.S. Patent No. 8,794,677

Due to the wide variety of operating conditions it may be subject to, Crystal
Engineering, as well as Distributors and Representatives of Crystal products, do not
warrant that this hose is suitable for any specific use. This hose is
not for use with compressed natural gas (CNG).
When used with gases, fuels (liquid or gas) and refrigerants, permeation (i.e., seepage) will
occur from inside the hose. In enclosed or unventilated spaces this permeation may result in
high concentrations of vapors which are potentially flammable, explosive or toxic. Care must be taken to protect hoses from snagging, kinking, bending smaller than the
minimum bend radius, and cutting. Any hose that has been damaged in any way should be
removed from service and discarded immediately.
